Systems and methods for synchronizing an appliance load to a local power generating capability
View Patent ↗An apparatus for synchronizing operation of one or more appliances to an amount of energy produced by a local power generator comprises a controller for reducing the power consumed by the one or more appliances in relation to an amount of power being generated by the local power generator. In one embodiment, the operation of the appliance(s) is controlled by the controller so that the system of appliance(s) and the local power generator does not consume any external energy (e.g., from a commercial power grid), despite variations in the amount of power delivered by the local power generator.
1. An apparatus for synchronizing operation of one or more appliances to an amount of energy produced by a local power generator, comprising:
a controller for reducing power consumed by the one or more appliances in relation to an amount of power being generated by the local power generator, wherein the controller is configured to determine a power generation capability by one or more power converters of the local power generator and to operate at least one of the one or more appliances based on at least one of the determined power generation capability and power consumption requirements for the one or more appliances.
2. The apparatus of claim 1 , wherein the controller is configured to determine the power generation capability by receiving measurements of at least one of instantaneous or average power generated by the one or more power converters.
3. The apparatus of claim 1 , wherein the controller is configured to generate a control signal for at least one of stopping, starting, or modifying operation of the at least one of the one or more appliances.
4. The apparatus of claim 1 , wherein the controller is configured to generate a control signal for operating the at least one of the one or more appliances at a reduced level of power consumption, equal to or less than power being generated by the local power generator, while power generation capability of the local power generator is determined to be below a threshold.
5. The apparatus of claim 4 , wherein the controller is configured to generate a control signal for returning the at least one of the one or more appliances to a normal level of power consumption when at least one of instantaneous power generation and average power generation by the local power generator meets or exceeds the threshold.
6. The apparatus of claim 4 , wherein the threshold is an average power consumption threshold.
7. The apparatus of claim 4 , wherein the threshold is an instantaneous power consumption threshold.
8. The apparatus of claim 3 , wherein the controller is configured to generate a control signal for operating the at least one of the one or more appliances in a normal power consuming mode while at least one of instantaneous power generation and average power generation by the local power generator meets or exceeds a threshold.
9. The apparatus of claim 8 , wherein the threshold is one of an average power consumption threshold and an instantaneous power consumption threshold.
10. A method for synchronizing operation of one or more appliances to an amount of energy produced by a local power generator, comprising:
reducing power consumed by the one or more appliances in relation to an amount of power being generated by the local power generator, wherein reducing the power comprises:
determining power consumption requirements for the one or more appliances;
determining power generation capability for one or more power converters of the local power generator; and
operating the one or more appliances based on at least one of the power consumption requirements and the power generation capability.
11. The method of claim 10 , wherein determining power generation capability comprises receiving measurements of at least one of instantaneous or average power generated by the one or more power converters.
12. The method of claim 10 , wherein the operating comprises generating control signals for at least one of stopping, starting, or modifying operation of at least one of the one or more appliances.
13. The method of claim 12 , wherein the generated control signals include a first control signal for operating the at least one of the one or more appliances at a reduced level of power consumption, equal to or less than power being generated by the local power generator, while power generation capability of the local power generator is determined to be below a threshold.
14. The method of claim 13 , wherein the generated control signals include a second control signal for returning the at least one of the one or more appliances to a normal level of power consumption when at least one of instantaneous power generation and average power generation by the local power generator meets or exceeds the threshold.
15. The method of claim 13 , wherein the threshold is an average power consumption threshold.
16. The method of claim 13 , wherein the threshold is an instantaneous power consumption threshold.
17. The method of claim 12 , wherein the generated control signals cause the at least one of the one or more appliances to operate at a reduced level of power consumption while at least one of instantaneous power generation and average power generation by the local power generator are at least one of at or below a threshold.
18. The method of claim 17 , wherein the threshold is one of an average power consumption threshold and an instantaneous power consumption threshold.
